Problems solved by technology

[0005] This application relates to a display panel, which is used to solve the problem in the prior art that due to the large size of the flexible folding screen and the long transmission distance, there is a delay in the transmission of the driving signal, which makes the first-level GOA and the last-level GOA There is a large difference between them, which leads to a decrease in the display effect of the display panel and abnormalities in the display screen. Moreover, as the number of display lines increases, the time required to refresh a frame of the screen also becomes longer, making it difficult to achieve a high refresh rate. question

Abstract

A display panel is disclosed. The display panel comprises two driving modules. A driving chip is arranged in each driving module along a first direction; each driving chip drives a part of GOA circuits in the second direction, that is, the first driving chip drives the first GOA circuit, the second driving chip drives the second GOA circuit, and the first GOA circuit and the second GOA circuit aredisconnected at a specific position of the display panel. The display panel has the beneficial effects that: firstly, the two driving modules are adopted, so that the number of display lines is increased, the influence of signal delay on a display picture is reduced, a high screen refresh rate can be realized, and the display effect is improved; and then, the first GOA circuit and the second GOAcircuit are disconnected at the central axis of the display panel along the second direction or a bending area, so that the picture display effect at the disconnection position of the display panel becomes better under the condition that normal display is not influenced.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel. Background technique [0002] As electronic products become more and more intelligent, OLED (Organic Light-Emitting Diode, organic laser display) display panels are gradually developing to large sizes, and their appearance forms are becoming more and more diverse. Using AMOLED (Active-matrixorganic light-emitting diode , Active Matrix Organic Light-Emitting Diode) surround-screen electronic products have also begun to enter the consumer market. Due to the large size of the AMOLED surround screen and the relatively complicated bending shape, the driving method has also been proposed under the premise of ensuring the display effect. higher requirement. [0003] Such as figure 1 As shown, when the existing flexible display panel 1' is working normally, the driving signal sent by the driver chip 11' is input by the GOA (Gate Driver on Array, array substrate row drivin...
